Found it at lowes. Comes in a repair pack. Can anyone tell me if I can get carb parts specifically the diaphragm in the bottom of the carb?
WJA
Reply: Ut21506 Homelite Primer Bulb

WJA

Hello 1142954,

I guess because of the low cost of the carburetor. The manufacture does not supply a repair or gasket kit for 308054001 carburetor. You think that they would supply them, I'm sure they would sell quite a few of them.

Question: Floating String Head Assy

psevans10

The entire string head assembly (and the rotating shaft inside of the boom assembly) silde out several inches, disengaging the rotating shaft from the engine on the other end of the boom assembly. How do I fix this?

Question: Homelite UTC21506 Primer Bulb

alfaalb

Can the primer bulb be purchased separately from the carburetor assy? If so, what is the P/N number & cost. Also is a gasket required? If so, what is the P/N & cost?

Reply: Homelite UTC21506 Primer Bulb

obviously this is a design flaw- the primer bulb only lasted 6 months- I have the same question- what is the bulb PIN - I will not buy a carb- the trimmer is not worth that price!!!
dcdon
Reply: Homelite UTC21506 Primer Bulb

dcdon

Sure you can.
Look at the carb to find make, or better just carry the bulb with you and your local lawn mower shop will have one.

It's the gasoline (E10) that causes it. When you put it away, pour the gas out and run it til it quits. Or use Stabil.

where can i purchase ia primer bulb
WJA
Reply: Homelite UTC21506 Primer Bulb

WJA

Hello jahmjh,

Because of the low cost of the 308054001 carburetor. The manufacture does not supply parts for it. You may want to do what dcdon suggested to do. And take it to a local small engine repair shop in your area, and see if they can match one up for you.

Question: Starter Problems

When cranking my mighty lite trimmer rope stays out. I have taken apart; when apart everything works fine. Is there a part in the starting assembly that is recalled? This trimmer has about 1 hr. of use. Its looks new runs perfect.

Clamp the two pieces together. drill holes in the piece that goes toward the engine so they line up with the pockets in the other piece but not the one with the rope in it. The drilled holes should line up with the pockets in the other piece. 2 holes for each pocket so the glue can force the air out as it goes in. Epoxy for plactic might work too, but I used hot glue gun and it's working so far. clean off extra glue so it's smooth as before and give it a try.
